IMPROVEMENT IN FIRE-ARMS.

Specification forming part of Letters Patent No. 148,476, dated March10, 1874; application filed August 11, 1873.

To all vwhom it may concern:

Be it known that I, FRANCIS C. MAUsER, of Ilion, in the county ofHerkimer and State of New York, have invented certain Improve` ments inFire-Arms, of which the following is a specification:

My invention relates to lire-arms; and the invention consists in anadjustable stop or holdfast for the ramrod, all as hereinafter morefully described.

Figure 1 is a side elevation of that portion ot' a gun containing myimprovements, with a portion broken away to show the improvements. Fig.2 is a transverse horizontal section on the line a: 0c of Fig. 1,looking from above downward. Fig. 3 is a transverse vertical section onthe line y `yof Fig. 1, and Fig. 4 is a perspective view ot the springdetached.

The drawings represent a gun made on what is known as the Remingtonsystem; but it is obvious that my improvements may be applied to othersystems also.

It is usual in making guns to bore a hole in a lug or portion of themetal forming the front end of the receiver or frame, directly under thebarrel, for the end of the ramrod to screw into, the hole in such casesnecessarily occupying a fixed position, and requiring great care andaccuracy in arranging the parts in order to bring them in such relationas to insure the rod entering this hole when the latter is insorted inthe stock.

To obviate this, and provide a stop or device that will automaticallyadjust itself to the position of the rod, I cut the recess in thereceiver entirely out at the front end under the barrel, leaving the twoside Walls projecting vertically downward, as shown in Figs. 1 and 3,the lower edge of this opening being subsequently closed by theinsertion ot' the guard-strap D, in the usual manner. In the inner facesof these side walls, near their 'front end, a semicircular groove, e, iscut, as shown in Figs. 2 and 3, to

receive the stop C. This stop I make of a piece of metal, which has itsends made of a circular form to t in the grooves e, as shown in Figs. 2and 3, it being made of a width vertically somewhat less than the depthof the recess in the receiver, so as to permit it to move verticallytherein, it being also made a little shorter than is necessary to lillthe grooves to permit this vertical motion. rlhis stop G has projectingfrom its rear side a lug, b, and it has bored in from the front a hole,which eX- tends into this lug, the mouth of this hole being madeconical, and considerably enlarged, as shown in Figs. l and 3. After thestop and receiver are thus formed, the former is placed in position byinserting it endwise into the recess i n the latter, and when oppositethe grooves e turning it until its ends engage in the grooves,

after which the guard-strap D is inserted, which prevents the stop Cfrom being turned so as to become disengaged or drop out, there beingleft, as shown in Fig. 3, sufficient space to permit the stop to bemoved vertically in its seat a short distance.

When thus arranged, it will be seen that as' the rod R is inserted itsend will enter the enlarged conical mouth of the hole in the stop, andthereby adjust the stop so as to bring its hole in line with the endofthe rod, which can then be screwed therein, thus producing vanautomatic adjustment of the stop to the position of the rod. l

Having thus described my invention, what I claim is An adjustable stopfor securing the ramrod in place, arranged to operate substantially asdescribed, whereby it will adjust itself to the position ot' the rodwhen the latter is inserted,

as set forth.
